Top 12 Best Computer Power Supplies 2017

Buying Guide

Many users choose a power supply based on total wattage alone, assuming that higher is always synonymous with better. Others pay no attention to their PSU selection at all, and settle for whatever abomination arrived with their machine. But considering how important a good power supply is to a system’s stability and long-term reliability, it’s a shame that PSUs get so little attention in comparison to sexier components like graphics cards and SSDs.

Best Computer Power Supply

For most computer users, the following chart will give a pretty good idea of how much power the computer is consuming and how big a power supply is needed.

An efficient PSU is a better PSU

certification levels

A power supply’s efficiency rating is important because higher-efficiency units tend to have better components, waste less power, and generate less heat – all of which contribute to less fan noise. A power supply with an efficiency rating of 80 percent provides 80 percent of its rated wattage as power to your system, while losing the other 20 percent as heat.
